The purpose of this study was to examine the reliability of the KT1000 arthrometer and the Lachman test. Twenty patients with a complete tear of the anterior cruciate ligament (ACL) were examined in a single session each. During the assessment, two physical therapists measured the anteriorâ€“posterior translation of the knee using both the KT1000 arthrometer and the Lachman test. The results showed that the KT1000 arthrometer has inadequate reliabilities and the Lachman test is a reliable measurement to determine the anteriorâ€“posterior laxity of the ACL deficit knee with good intra-rater reliability as well as inter-rater reliability.
